Biopolymer coatings market can be segmented based on product type into cellulose, starch, protein, and lipid-based coatings.
Cellulose-based coatings are derived from natural sources such as wood pulp and cotton. These coatings offer excellent barrier properties, mechanical strength, and flexibility. They are commonly used in packaging applications for food and beverage products, as they provide protection against oxygen and moisture, thus extending the shelf life of the packaged goods.
Starch-based coatings are primarily sourced from corn, wheat, and potatoes. These coatings are biodegradable and renewable, making them a sustainable choice for various packaging and coating applications. They offer good adhesion to substrates and can be used in a wide range of industries including food, pharmaceuticals, and cosmetics.
Protein-based coatings are derived from sources such as soy, wheat, and milk proteins. These coatings possess excellent film-forming properties and are used as edible coatings for fruits and vegetables to improve their shelf life and reduce food waste. They also find applications in the pharmaceutical and nutraceutical industries due to their biocompatibility and ability to enhance the stability of active ingredients.
Lipid-based coatings are sourced from natural sources such as vegetable oils and animal fats. These coatings provide moisture resistance, lubricity, and gloss, making them suitable for various packaging and coating applications. They are commonly used in the food industry to coat confectionery products, bakery goods, and snacks to improve their appearance and shelf life.
